Service Host (svchost.exe) Using 99% CPU

    Question

  • Hey guys-

    I know this question has been asked for other Windows OS's, but none of their fixes apply on Windows 8.

    When I log in, everything is fine, everything is very smooth and even faster than when I used Windows 7, but after a few minutes my CPU becomes locked at ~99%, mostly because of svchost.

    As it appears on Task Manager, the process is Service Host (No Impersonation). The sub-processes are Function Discovery Resource Publication, SSDP Recovery, Time Broker, and UPnP Device Host. I tried several fixes that worked in XP or 7, but they either can't be used in 8 or detect nothing is wrong.

    This is the only thing that makes me dislike 8 so far, a fix would be fantastic.

  • The uPNP service causes the high CPU usage while waiting for compatible devices:

    disable the service and try again.

  • Hi Andre,

    I am also facing the high CPU utilization problem by svchost.exe


    NO, you have a virus/malware with the name svhost.exe (without c) which uses your CPU to do some calculations.

    C:\Users\Pushkar\AppData\Roaming\data\svhost.exe -o http://pool.darkcarder.com:8332 -O albert1408.22:80uhkaw3cwn2pg63nz

  • Can you please check mine - just started having this issue as well?

    https://dl.dropboxusercontent.com/u/24659606/highCPUUsage.etl

    Thank you.

    You have 2 issues.

    1st: the DHCP client tries to renew the TCP config and this causes CPUusage:

    (dhcpcore.dll!DhcpRenewThread/dhcpcore.dll!SendDhcpRequest)

    2nd: Writing a firewall rule causes cpu usage (mpssvc.dll!RPC_FWIndicatePortInUse, mpssvc.dll!CDfwEngWriter::GenerateFwRule)

  • in your case the CPU usage comes from Superfetch service. But I don't recommend you to disable it.

    YOu should remove AVG and see if this improves the situation. There are 3 AVG tools which also generate a high CPU usage.

  • Make a xperf trace to see the cause. Install the WPT (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt-en-us.aspx), open a CMD prompt with admin rights and type this:

    xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d highCPUUsage.etl

    after you captured 30s of the cpu usage, go back to CMD prompt and press a key to stop the logging. Now compress the highCPUUsage.etl as 7z (LZMA2, ULTRA) to reduce the size. Upload this file to your SkyDrive or Dropbox and post a link here.


    If you have upgraded from Windows 8.1 and you have a high CPU usage that you can't detect in Process Explorer like shown here:





    you have an issue with a scheduled task. Look at the green "sdclt.exe". This means the sdclt.exe is started very often. This causes the CPU usage.

    You can see this best in ProcessMonitor:





    The solution is to disable this task in the task scheduler:




    Also phone the Support and open a case so that MS can fix this issue.

    in your case the cause is the "Software Protection" service which checks if your system is genuine.

    The svchost.exe usage is smaller and comes from the Firewall service (FirewallAPI.DLL!FwEnumRules). How much Rules do you have defined?

    NO, you have a virus/malware with the name svhost.exe (without c) which uses your CPU to do some calculations.

  • Hey guys-

    I know this question has been asked for other Windows OS's, but none of their fixes apply on Windows 8.

    When I log in, everything is fine, everything is very smooth and even faster than when I used Windows 7, but after a few minutes my CPU becomes locked at ~99%, mostly because of svchost.

    As it appears on Task Manager, the process is Service Host (No Impersonation). The sub-processes are Function Discovery Resource Publication, SSDP Recovery, Time Broker, and UPnP Device Host. I tried several fixes that worked in XP or 7, but they either can't be used in 8 or detect nothing is wrong.

    This is the only thing that makes me dislike 8 so far, a fix would be fantastic.

    hey im having the exact same problem as well

    Thank you, CP

    Friday, September 13, 2013 11:00 PM
  • I don't know if people are still having this issue, but this is what I do when something like this happens:

    1.) I go into task manager to locate the CPU hog, then trace it to Services, after locating the services causing the CPU overuse, I reset them. I don't recommend stopping anything, just restart it and see what happens. (This may take a short while to have an effect, or you will need to repeat this a few times.)

    2.) The other fix that seems to work for me is to simply restart my Win8 PC.

    These sort of problems usually happen to me when I put my PC on Standby or Hibernate (like Time Broker for instance). I'm not sure why this happens (this topic for another forum)...

    Like I said, this is what happens to me. This may not be the same with other people, but I'd thought I'd share anyways.

    the trace shows that you have cpu usage caused by iTunes.exe which causes some cpu usage from the audio service.

  • the small cpu usage comes from coreServiceShell.exe and YCMMirage.exe.

    To see the RAM usage, too you must run this command:

    xperf -on latency+ReferenceSet -stackwalk profile+VirtualAlloc+VirtualFree -buffersize 1024 -MaxFile 1024 -FileMode Circular && timeout -1 && xperf -d HighCPUUsageWithVAlloc.etl

    you have no real CPU usage, the high cpu usgae comes from the sdclt.exe which is started over and over again.

    Disable the confignotification task in the task scheduler.

  • Hello Andre, 

    I have a strange problem as well. If I am watching a youtube video my laptop begins to lag after two or so minutes of inactivity. But if i move my mouse (wireless bluetooth mouse) or press a key on the keyboard the lag stops. It always happens even in games if I use my wireless controller to play and don't press any keys or use my mouse for a few minutes.  Here is my .etl file: https://www.dropbox.com/s/dpqy7tu6kuw7znt/highCPUUsage.7z

    Thank you,

  • The trace shows some CPU usgae spikes by a tool called (fnfdeiocg.exe) which uses OpenCL (igdfcl32.dll). I think this is a malware (based on the file location: C:\Users\Iulian\AppData\Local\Temp\pjruprzcodwy\fnfdeiocg.exe -c "C:\Users\Iulian\AppData\Local\Temp\pjruprzcodwy\cfgb").

    Looks like this tool uses your hardware for some calculations. Boot into safe mode, run AutoRuns, cleanup the tools and do a virus scan.

    in your case it is WindowsUpdate which checks for updates.

  • Hi Andre,

    I have a similar problem and i can't get your instructions at the top of this thread to work using the cmd prompt.

    I have usage issues. I am using w8.1

    Also see the cmd prompt shot.

    I can't put images into here so have included them in a dropbox file; https://www.dropbox.com/s/5j42wqgzgup8sb4/CPU%20Usages%20issues.pdf

    Please can you help

    Sorry for the confusion.  I forgot to copy the file up.  Here is a new link - https://www.dropbox.com/s/52ikztzn3jseya6/highCPUUsage.zip  I have noticed that my Microsoft bluetooth keyboard and mouse have issues during these times of high utilization as well.  I thought it was just when the CPU reached 100%, but I am having the issue right now and the processor only shows about 60%.  I am running 8.1 on an original Surface Pro.

    Thanks Andre.

    Thank you for your help.  I got a little over anxious and deleted the whole "Windows Backup" folder out of the task scheduler and rebooted and the issue did not come immediately back as it has before.  I suspect this has taken care of the issue and I hope it has not caused any ill effects.  Since I am working on a Surface Pro I do not know of an option to remove the hard drive and rename the file mentioned above through accessit from another computer.

    Again thank you for your help.

  • Could you have a look at my file too. ;-)

    Much appreciated.

    the DNS client services loads the Host file into the RAM and this causes the periodic svchost.exe usage:


    After joining the forum 4 years ago, I'll leave it soon. The abusive behavior of moderator and CGS users to repost already posted answers or only posting generic and useless replies like "Do a clean boot" to nearly all question and marking their own replies as answer reduces the quality of the forum dramatically. I'm tired of such trolls and no longer wasting my spare free time. If you're an user who whats high quality answers and help by analyzing your crash dumps, xperf/xbootmgr trace or CBS logs ask on msfn.org, I'll take a look at them. After December 1st 2013 I'll only post to topics where I already replies to. So hurry up and ask your question.

  • The host file was full with lines excluding ads websites (genrated by spybot). No need for that anymore when using Adblocker in Chrome.

    I see that you are helping people with this type of problem. Any chance you can look at my etl file and let me know what is causing the high CPU usage? My laptop was running fine then all of the sudden it started lagging and using 98% of the CPU. I appreciate your help!
